Principle of the present invention is: in the present invention, owing to being provided with tube core (namely by graphite core retainer plate in forming graphite cover, the structure that heat transfer jacket and water inlet pipe form, referred to as tube core), tube core can for molten cast iron provides sizing and supporting role in the cooling forming process of molten cast iron, make cast iron inner hole of pipe shaping, coordinate outside forming graphite cover again, molten cast iron is finally made to be directly formed to cast iron tubing in by the process of forming cavity, avoid in prior art and need borehole on cast iron bar just can produce the problem of cast iron pipe, specifically, all parts in the present invention plays a role like this:
Holding furnace is the usual means in continuous casting process, and its Main Function is the molten cast iron holding high temperature;
Forming graphite cover is also usual means when adopting continuous casting process making cast iron bar in prior art, and its effect utilizes the high temperature resistant sticky glutinous characteristic of graphite to carry out moulding to the outline of product;
The effect of graphite core retainer plate utilizes the high temperature resistant not sticky glutinous characteristic of graphite to carry out moulding to the Internal periphery of product; The supporter that graphite core puts is mainly used in being formed between graphite core retainer plate and forming graphite cover supporting, with ensure graphite core retainer plate and forming graphite cover between centering and axiality, simultaneously, duct on supporter is that the circulation of molten cast iron provides passage, the molten cast iron of high temperature enters in forming cavity by the duct on supporter, specifically, when supporter adopts multiple spreader, molten cast iron flows in forming cavity by liquation entrance, during supporter employing supporting disk, molten cast iron flows in forming cavity by the axially extending bore on supporting disk;
The effect of heat transfer jacket, mainly for graphite core retainer plate provides mechanical support, avoids graphite core retainer plate to rupture, in order to provide good supporting role, heat transfer jacket need make of metal material, but because the temperature of molten cast iron is very high, heat can be delivered in heat transfer jacket by graphite core retainer plate, easily softening transform is there is under heat transfer jacket hot soak condition, so the present invention is also provided with water inlet pipe in heat transfer jacket, cooling water enters from water inlet pipe left end, flow in heat exchange chamber from water inlet pipe right-hand member, finally flow out from the radial direction through hole of heat transfer jacket left end, by the flowing of cooling water, the heat be deposited in heat transfer jacket is just constantly pulled away, this guarantees heat transfer jacket and be in lower temperature all the time, softening transform can not be there is, the structural stability of graphite core retainer plate is finally made to be protected.
Preferably, described forming graphite cover is outer is socketed with radiating sleeve, and radiating sleeve inwall and forming graphite overlap wall contacts; Be provided with helical pipe in the housing of radiating sleeve, helical pipe is coiled in the periphery of radiating sleeve endoporus, and helical pipe two ends are communicated with external environment.Radiating sleeve is the usual means in continuous casting process; its effect is for forming graphite cover provides support protection; in addition, the helical pipe on radiating sleeve, except playing except cooling effect to radiating sleeve, can also play certain regulating action to the cooldown rate of the molten cast iron in forming cavity.
In order to improve result of use of the present invention further, the present invention also proposes following preferred version for the structure at the second installing hole place: be provided with an adapter sleeve in described second installing hole, adapter sleeve right-hand member is connected with graphite core retainer plate, and heat transfer jacket is passed in adapter sleeve; The water outlet be communicated with radial direction through hole is provided with in adapter sleeve.
